.asp giving 404

On a recent test I got FTP write access to a web server which had an
ASP based site on it. I uploaded an ASP shell and tried to browse to
it but got a 404. I uploaded it to a directory that had directory
listing enabled and confirmed the file was there but again browsing to
it gave a 404.

I uploaded a text file and image and could browse to both of those fine.

I also tried downloading an existing page and modifying that then
re-uploading it but didn't have permission to overwrite the file.

I vaguely remember something to do with file permissions having to be
set correctly for ASP to run from years ago when I did some dev work
in it but can't remember. Can someone tell me what was likely to have
been going on and if there is any way around it given the access I
had?
